Abstract
An integrated intravenous (IV) administration set includes a flow stop having a tubing fitment and a housing, the flow stop configured, in a first position, to prevent a flow of a fluid through the tubing, and in a second position, to permit the flow of the fluid through the tubing, the tubing fitment comprising a protrusion configured to receive a tubing. The IV administration set also includes an electronic flow sensor disposed within the housing, the electronic flow sensor configured to measure a flow of a fluid in the tubing, and one or more conductive connections configured within the housing and configured to provide electrical power to the electronic flow sensor. The flow stop is shaped to be loaded and engaged to a receptacle of an infusion device, and shaped to cause, when loaded and engaged, the one or more conductive connections to engage with a corresponding conductive connection provided by the infusion device to activate the flow sensor based on a power flow from the infusion device.
